7 Options
7.1 Outlet nozzle
The outlet nozzle replaces the Air-Injector. The external dimensions of the unit
remain the same. The weight is reduced:
■ Size 6: – 15 kg
■ Size 9: – 21 kg
The air discharge angle cannot be adjusted. Units with outlet nozzle are well-
suited for applications with lower comfort requirements and for large mounting
heights (e.g. in high-bay warehouses).
7.2 Suspension set
For ease of installation of the units, there are suspension sets available (complete
with nuts and bolts).
7.3 Air filtration
For hygiene reasons, Hoval recommends always fitting TopVent ® TG units with a
filter.
Filter box
A filter box with 2 bag filters can be installed for the purpose of filtering the
recirculation air. The modular construction made of aluzinc sheet metal with
2 sliding doors makes it easy to replace the filters.
A pressure difference control device is installed for automatic monitoring of the
filter. It shows when the filters have to be changed.
